For blinds that sit inside a window frame, measure the opening carefully and compare it with the product’s stated sizing rules before ordering. The ACHIM cordless mini blinds are the closest match for buyers seeking traditional slats and specified fit guidance. The Persilux cordless roller shade is better for shoppers who prefer fabric over slats, but its listing does not provide the same detailed width deductions.
| Product | Best For | Style |
|---|---|---|
| ACHIM 34 x 64 Pearl White | Wider openings | Vinyl mini blind |
| ACHIM 32 x 64 Pearl White | Mid-size openings | Vinyl mini blind |
| ACHIM 27 x 64 Pearl White | Narrower openings | Mini blind |
| Persilux Light Filtering Roller Shade | Fabric-shade preference | Cordless roller shade |
| ACHIM Morningstar 28 x 64 | White vinyl slats | Mini blind |
ACHIM 34-Inch Cordless Mini Blinds
Best for: Buyers whose measured window opening suits the 34 x 64-inch stated size and who want white, light-filtering slats. These vinyl blinds have a cordless design and one-inch slats. The listing says the actual blind is half an inch narrower than the stated size and is intended to fit windows 3/8 inch smaller or 1/2 inch wider than the stated size.
The stated fit guidance makes this option useful for planning an inside-frame installation. Its lightweight vinyl construction is described as resisting warping, fading, and sagging. Choose it if you want a conventional mini blind with no hanging cords. Measure the frame rather than assuming the listed width equals the blind’s actual width; the product information does not specify installation details for every frame type.
ACHIM 32-Inch Cordless Mini Blinds
Best for: Shoppers comparing a mid-width opening with a 32 x 64-inch blind. This pearl white option uses vinyl slats, filters light, and operates without cords. The listed actual blind width is half an inch less than the stated size, and the fit guidance allows for a window 3/8 inch smaller or 1/2 inch wider than the stated size.
The product listing also notes a fashion headrail with hidden brackets for easier installation. That detail may suit buyers who want a less prominent bracket appearance. Select this model over the 34-inch version when the measured opening better matches its size. Its light-filtering design is not described as blackout, so choose another treatment if blocking most incoming light is the priority.
ACHIM 27-Inch Cordless Mini Blinds
Best for: Buyers looking for a narrower 27 x 64-inch light-filtering blind. The listing describes a cordless mini-blind design with one-inch slats and a pearl white finish. It also gives the same fit guidance: the blind is half an inch narrower than its stated size and is intended for windows 3/8 inch smaller or 1/2 inch wider than stated.
This size is a better starting point than the wider ACHIM options when the frame opening is narrow. The listing identifies the material as polyester, while its feature text also refers to vinyl; verify the current material details on the product page if material is important to your choice. Do not select by nominal width alone—compare the actual measured opening with the stated fit range.
Persilux Cordless Light-Filtering Roller Shade
Best for: People who prefer a continuous fabric shade instead of adjustable slats. The Persilux shade is described as cordless, light filtering, and made with linen fabric. The listing says the fabric provides privacy and UV protection, and mentions a shading strip intended to reduce light leakage at the top.
Choose this option if fabric texture and a roller-shade appearance matter more than traditional mini-blind slats. The listing refers to custom sizing, but the provided product details do not give a specific finished-width deduction for an inside-frame fit. Confirm the size-selection instructions before ordering. It is a light-filtering treatment, so do not assume it fully darkens a room.
ACHIM Morningstar 28-Inch Cordless Blind
Best for: Buyers whose window opening suits a 28 x 64-inch white vinyl mini blind. This cordless model filters light and has one-inch slats. Its listing says the actual blind is half an inch narrower than the stated size and provides a fit range based on the stated measurement.
This is a practical comparison against the 27-inch ACHIM blind when the opening is close to either size. Its cordless construction is intended to avoid dangling cords, and the vinyl is described as resisting warping, fading, and sagging. Check the precise opening width before choosing between the two. The listing does not describe this blind as blackout.
Buying Guide: Choosing Blinds For Inside A Window Frame
How should you measure for an inside mount?
Measure the width of the window opening in more than one place and use the narrowest measurement when checking fit. Measure the height as well, and note whether handles, locks, or other hardware project into the opening. Follow the specific product’s sizing instructions: the ACHIM listings state that their actual blind width is half an inch less than the stated size.
Should you choose mini blinds or a roller shade?
Mini blinds use slats and are the closer match for shoppers searching for jalousie-style window coverings. A roller shade uses one piece of fabric and creates a different look. The ACHIM options specify one-inch slats; the Persilux product is a linen-fabric roller shade. Compare the style and light-filtering preference before selecting a size.
What matters for light and privacy?
All five products are presented as light-filtering options. That means shoppers should not treat them as guaranteed blackout coverings. The Persilux listing specifically describes privacy and UV protection, while the ACHIM blinds are described as filtering light. Consider whether you need adjustable slats, a fabric surface, or a darker room when comparing them.
Are cordless blinds a useful feature?
Each listed ACHIM mini blind and the Persilux shade is described as cordless. The ACHIM listings say the design avoids tangled cords and is child and pet safe. Buyers should still use and install any window covering according to its product instructions.
